Ring Chime Will not connect to my WiFi

HELP !!! I have tried everything to resolve this connection problem with my Chime that continues to fail to connect to my home WiFi.I have spoken to Ring support and must have spent 1 hour on the phone trying everythin they suggested. In the end I was sent a replacement Chime. Which did connect briefly and has since failed repeatedly to connect . The Doorbell works fine the Chime will not connect . I have spend hours trying to sort it. I have…Deleted device, added as anew device, used a different WiFi network, tried to connect with a different iPhone, held reset button, rebooted Router, moved Chime very close to Router, removed Nord VPN from iPhone, checked ‘’Location settings “… Still not connecting. My WiFi signal is 50-100 mbps. I am so frustrated I do not know how to resolve this … Any one any thoughts???
